Yeah, Part Of managed to debut at #1 against Whitney and Adele and Wide Awake was in the middle of CMM and STIUTK, two of the best digital songs ever. Now that I think about it: Hot N Cold was agains two T.I. smashes, TD Love The Way You Lie and Dynamite, LFN Party Rock Anthem and TOTGA We Found Love and Sexy & I Know It.
Not to mention Roar and Blurred Lines

Taylor is the only major star in the game right now, I wish K4 will have this kind of competition.
